yided ontheunder. side of'the shuttle base. These shafts and pinions are so spaced along the trackway, and the shuttle base 18. has .such length, thatIat least one driving pinion 23 is always in mesh with the'teeth "on the shuttle base .whereby the shuttle ispassed on' from each inion to the next without incondition ma be'alsoexpressed by the statement that t e length of the shuttle base in the direction .of its travel is greaterithan the space betweenany two .driving inion's; Preferably, however, the base-is ong" enough to overlie nearly .the whole of two of these spaces, being thereby -at once. As all the bevel 21 are of the same diameter and-pitch, and all the 'ving pinions28 arealso of the-same diameter and pitch, the shuttle is drive]: 11.

166' engaged most of the time with two pinions 1 smoothly at a uniform rateof speed and base, to which it is fastened by any suitable means, and one end is directed toward the weaving point at the center of the loom while in the other direction the bar extends over and around the rim of the head, and then downward, with an-inclination in part toward the post. This bar may lee considered as an angularly formed frame-which has a horizontal part 25 overlying the base or Slide 18 and a dependingpart 25 below the head and beside the post of the frame. This depending part is provided near its lower end with-a supporting bracket 26 whereo-n a bobbin holding spindle 27 is mounted, and it is provided at a distance above this bracket with a secondbracket or spindle retainer 28 by which the upper end of the s indle is held and made steady. These brac ets pro ject from the bar member 25 tangentially of the loom frame and preferably in the opposite direction to the travel of the shuttle.

A bobbin, or spool, or tube 29', on which is wound a supply of filling yarn 30, is adapted to be slipped'on and off from the spindle 27';

and in order to permit mounting and dis- 'mounting of such a bobbin, etc., the spindle is pivoted to the lower bracket and detachably' connected with the upper bracket in such manner that it maybe swung clear of the upper bracket. Preferably the arrangement of the s indle is such that this swinging movement ta es.- place in a plane more or less radial to the Ioombut not necessarily so. A pivot 31 supported in lugs on the bracket 26 holds the lower end of the spin dle, while a locking pin 32 secures the upper end of the spindle detachably to the upper bracket. This locking pin projects from the end of the spindle and is partly contained in a socket therein.v It is acted upon by asprmg 33 pressing against a head 34' and reacting I against a plug 35 fixed in the end-of. such socket, whereby it is normally pressed in:

.w'ard but may be pulled'out by means of its 4 head 36. In the sideof the bracket 28 is a" slot 37;adapted to admitthe pin 32, and in the upper faceof the bracket is a recess 38 adapted to admit a collar 39 on the locking pin,such recess and collar being wider than the slot. Thus when, said collar occupiessaidrecess the spindle is locked in upright position, but itmay be readily unlocked and swung aside by raising the locking pin head and moving it outward. Although this is a convenient mode of securing the spindle and is preferred, other means of accomplishing the same result may be used within the scope for which I' claim protection.

The distance between the brackets 26 and 28 limits the possible length of the filling thread bobbin, and the diameter of the head and the distance which must be preserved in a weave room between adjacent looms limit thediameter of' the bobbin. Preferably the frame member 25 between the brackets is upright and parallel with the post frame, While between the upper bracket and its junction with the horizontal member 25 it is inclined for the double purpose of locating the bobbin as near as practicable to the post and thereby utilizing the space beneath the ,head, and of bringing the center of gravity of the entire bobbin underneath the shuttle base. 1

A spreader for opening-the shed to permit passage of the shuttle and bobbin without interfering with the Warp yarns is constructed of two pairs of bars 40, 41 and 42, 43, respectively, arranged adjacent to the upper and lower ends of. the bobbin and supported by a rod or equivalent frame '44,

45, 46 which is secured to the forward edge or part of. the-rigid shuttle frame bar 25 respectively; Thatpart of the spreader supporting frame which is designated 45 is an upright member substantially parallel to and inthe path traveled by the center of the bobbin and the inner spreader bar of each pair is rigid to the frame, but the outer bars or members 40 and '42 are pivoted at their order that they may be swung aside to per mit the displacement of the bobbin spindle as previously described. Braces 47 of any suitable character limit the closing in movement of these hinged spreader members. Other braces may be arranged'between the rigid shuttle frame bar and the spreader frame if desired or necessar .near the bend and the lower end of the latter,

forward ends to the supporting frame in to make the spreader .sufliciently rigid. I mple space is afforded-for sufficient bracing without i'nterfering with the bobbin or with the traverse of the shuttle thread from the bobbin to the weaving point. I

The shuttle thread 48 passes from the1bobbin through an eye49 in the adjacent part 25" of the shuttle frame and thence arounda guide'wheel 50, pivoted in a bracket which is attached to the upright member 45 of the spreader frame. Thence the thread passes through an eye 51 in the inclined part of the shuttle frame, and over guides 52, 53 which guide it around the rim of the loom frame head. Finally it passes through an eye in a shoulder 54.at the inner end of the shuttle frame. member 25", and through suitable guideways 55 formed in a packer 56, to the packers previously used in this art.

The diameter of the tube being woven is controlled by the cooperation of said packers 56 and a gauge tube 60'through which the tube passes as soon as woven. The gauge tube is mounted in a manner permitting its adjustment and replacement by tubes of other sizes in a manner well known in this art and, therefore, not described in detail here. A take-up mechanism for the finished tubing is indicated in Figure 1, but not shown in detail because I'may' use any of the mechanisms for this purpose'already familiar in the art.

The driving shaft 19 is tubular in order to permit passage through it of anyconstruction, such as a hose lining or cable, about which a fabric casing is to be woven; and it permit in order to admit passage of as large is made with as large a bore as strength and available space within the hollow post will linings, cables, etc. as possible. Itrotates in bearings of any suitable character, and is supported in any suitable way.- In the arrangement here shown its supporting means consists of a thrust bearing 61 which may be a ball bearing and rests on the upper end of the post 10. A cam 62 secured to the shaft for operating the heddle mechanism, presently to be described in detail, serves as a collar on the shaft which rests upon the thrust bearing. On the lower end of the shaft is a pulley 63 or eqivalent'means for receiving power from an outside source.

The heddle motion is located below the path of the shuttle, preferably at the base of the central post, in order to give room. for a long shuttle mounting. The heddles 64, 65 are arms carried by shafts 66 and 67, respectively, arranged parallel to one another and tangent to a circle concentric with the loom frame. The entire heddle motion consists of a series of groups, each group consisting of the shafts and arms or fingers just described, and these groups are arranged about the central post, being provided in such number and each of such length as to conform as closely: as practicable to a circular outline.

Obviously as the shafts are straight, the greater the number of groups, the more closely will these groups conform to the circumference of a circle. I have found that eight groups give close enough approximation to the circular outline for practical purposes without involving too great a multiplication of driving connections.

Of the two shafts of each heddle group one is outside of the other and at a somewhat lower level, an arrangement which is conducive to the best effects in opening and changing the shed. At their ends these shafts are supported rotatably in brackets 68, and to the inner shaft of the group is affixed a gear segment 69. Meshing with the segment is a reciprocating rac'k.70 carried by the lower end of a bar 71 which passes through-a guideway in the head 11 and carries a stud or roll 7 2 which enters a groove 7 3 in the cam 62 previously described. The lower end of the bar, which carries the rack, is guided by an open chair 7 4 which is bolted to the outside of the post 10. Transmission means between the two shafts is provided of such a character as to cause opposite and substantially equal oscillation of the-shafts at the same time. One character of means suitable for this purpose consists in an arm 75 on one of the shafts carrying a pin 7 6 which occupies a notch or slot 77in an arm 7 8 on the other of the shafts. Intermeshing gear segments or other equivalent machine elements may be used, however, with like effect for the and through eyes in a bar 782 beneath the base to the several heddle arms. Other guidin}; means known to those skilled in the art to which this invention relates may also be used. The heddle arms have eyes through which the warp threads pass and from which they extend around the rim of the head 11.

Grooves 7 9 are cut in the bounding lips and cross the bottom of the shuttle guideway in sufficient number and so arranged as to accommodate all of the warp threads with a substantially equal angular spacingabout the center of the loom. With each change of the shed half of the warps lie n these grooves beneath the shuttles. The alternate warps pass over and outside of the shuttles. In order to reduce interference of the shuttle frames with the outer warps to the minimum, the frame bars 25 are made as narrow as possible in that dimension which causes displacement of the warp threads, and the nec-' essary strength is provided by widening them" i in the direction in which they travel, and

they are reduced intliickness to a'thin edge from their rear toward their advancing sides.

In the operation ofthe loom the central shaft 19 is driven by the pulley 63 orequivar lent means and in turn propels the shuttles in their circular path by means of the gear 20, pinions 21, shafts 22 and pinions 23. At I v the same time the cam 62 actuates the heddle motion to change and open the shed in ads to a substantially upright position and the heddle fingers on the outer shaft are swung from a position inclined toward the post to an outwardly inclined position, while on the up travels of the racks the reverse action takes place. Of course the cam groove 73 has a suflicient amount of offset axially to give the required movement to the rack, and the groove likewise has a large enough number of such oflsets to impart one of these movements to each rack in advance of each shuttle. If there are two shuttles the rack is moved once upward and once downward with each revolution of the cam, while if there are four shuttles each rack is given two of these movements. This design, even though the outside diameter of the loom is small, provides room for a cam large enough to make a quick change of the shed between shuttles without making the inclines of the cam groove too steep for smooth and easy running.

A wide enou h opening is given to the shed by the'heddle 'ngers to admit the advancing end of the spreader frame, and having once entered the shed formed by any heddle group, the side spreader bars 40, 41, 42, 43 hold the warp threads away from the bobbin while the upper and outer bar 40, in combination'with the supporting rod 44, clears the outer warps from the upper part of the shuttle frame 25. The upper frame member 25 of the shuttle slips under the outer warps.

If necessary, in order to prevent displace ment of these warps by the shuttle, I may provide a fixed outer ring having fingers or teeth arranged beside the correct normal positions of the warps, in accordance with a well known and frequently followed practice. A suitable location for such ring is indicated in dotted lines at 80 in Figure 2, the shuttle frame bar having cross groove 81-across which the warps bridge and into which the fingers of the retaining ring may project.

One of the conspicuous advantages derived by reason of this invention is that a loom of relatively small outside dimensions can be set up to weave a verylarge number of ends in a warp, and thereby to make tubes of large diameter. Since any number of warps less than the maximum may be Woven in the same loom, it follows that a wide range of sizes of tube may be made. Translating this advantage into terms of factory practice, a larger num ber of looms capable of weaving tubes of the maximum size may be installed in a given floor space than has previously been possible, and a greater variety of tubing may be ob ta'inedfrom the operation of the same looms,

manna? known construction and operated by heretoloading of the shuttles than has been possible heretofore. This is obviously due to the fact that the bobbin is carried below the head of the machine frame and close to the post, which gives room for a bobbin of large diameter, and to the fact that the long vertical space between the heddle motion and the frame head enables the length of the bobbin to be greater than heretofore.

The heddle elements may be made of sheet metal stanipings and may, therefore, be made very thin, for ample room exists for them to be made as wide as is necessary to give strength. Hence a large number of these elements may be mounted upon a shaft of short length. They may be so mounted in many ways, with or without provision for adjustment about their supporting shafts. @ne possible construction consists in stringing the elements on a sleeve 82 and securing them thereto by keys, the sleeve being rotatable on the shaft and carrying one or more set screws 83 by which it may be secured. Another possible construction exists in so bending the strip of which the finger is formed that a short tongue 4 84 is provided parallel to the main body of the finger and united thereto by a web 85., The tongue and the adjacent part of the linger body, being perforated with alined holes, may be slipped on the shaft, and a setscrew 86 passed through a threaded hole in the web 85 secures the linger. it is also possible to adjust both shafts and their associated heddle elements in unison by removing the chair i i and slipping the rack 70 out of mesh with the gear segment 69, shifting the heddle elements into the desired position, and reen-' gaging the teeth of the rack with other teeth of the segment.

It will be evident that various changes may be made in the construction and arrangement of the loom and the several parts thereof without departing from the spirit of the invention or from the scopein which I claim protection.

The title and description of the machine herein described as a circular loom are not intended to import a limitation to machines included within the most narrow definitions of looms or to exclude machines known in the art as braiders of the circular type. The new principles of this invention are applicable to machines which are variously operated 'for weaving or interlacing strands, whether in the form of a circular weave or fi ClI'ClllfiI' braid, and whether such machines are called looms or braiders.
